Product Sheet Soda Ash
A weak base that is soluble in water and dissociates into sodium (Na) and carbonate (CO3) ions in solution.
Soda ash is the common name for sodium carbonate (Na2CO3). It is a weak base that is soluble in water and dissociates into sodium (Na) and carbonate (CO3) ions in solution.
Calcium is present in many makeup waters and formations. It can cause flocculation of the mud, resulting in increased rheology, gel strengths, and fluid loss. High-filtrate calcium causes precipitation of calcium-sensitive additives, such as POLY-PLUS high-molecular-weight liquid clay inhibitors and RINGFREE polymeric thinners, which are the most sensitive. Cellulosic polymers are only slightly calcium-sensitive and tolerate moderate levels of filtrate calcium.

Soda ash is an alkaline material that can cause irritation to eyes, skin, or respiratory tract. Soda ash should be added slowly to the mud system either by mixing through the hopper or chemical barrel. Do not mix soda ash with other chemicals, especially caustic soda or lime. When using a chemical barrel, mix soda ash into a full barrel of freshwater and provide adequate agitation.
Soda ash is a globally available commercial chemical and is packaged in 100-lb [45.4-kg] and 50-lb [22.7-kg], multiwall, paper sacks. Store in a dry area away from water or acids.
